Khē
Khē, or Keheh, is a letter of the Arabic script, used to write in Sindhi. It is equivalent to ख in Sindhi's Devanagari orthography.
In Arabic, it is considered a variant form of kāf, notably or, and is used in rasm writing of the Arabic language. It is the predominant form of kāf in the Perso-Arabic script.
But in Sindhi, khē and kāf are differentiated: khē is used consistently for, and kāf for. This is similar to the history of I and J, and of U and V, in the Latin alphabet.
